Script error

[night wagon]

It keeps saying Im attempting to put userID with nil. Im not sure how to fix this. Here is the script:
local Players = game:GetService("Players")
local DataStoreService = game:GetService("DataStoreService")
local RunService = game:GetService("RunService")

local dataStore = DataStoreService:GetDataStore("Test")

local function givePlayerCurrency(player: player)
while true do
task.wait(1)
player.leaderstats.Strength.Value += 1
player.leaderstats.Cash.Value += 1
end
end

local function setupPlayerData(player: player)
local userID = player.UserId
local key = "Player_"..userID

local leaderstats = Instance.new("Folder", player)
leaderstats.Name = "leaderstats"

local strength = Instance.new("IntValue", leaderstats)
strength.Name = "Strength"
strength.Value = 0

local cash = Instance.new("IntValue", leaderstats)
cash.Name = "Cash"
cash.Value = 0

local success, returnValue
success, returnValue = pcall(dataStore.GetAsync, dataStore, key)

if success then 
    if returnValue == nil then
        returnValue = {
            Strength = 0,
            Cash = 0,
        }
    end
    
    print(returnValue)
    strength.Value = if returnValue.Strength ~= nil then returnValue.Strength else 0
    cash.Value = if returnValue.Cash ~= nil then returnValue.Cash else 0
    
else
    player:Kick("Error in your loadout. Please rejoin.")
    print(player.Name.."Data Loading Error")
end
givePlayerCurrency(player)

end

Players.PlayerAdded:Connect(setupPlayerData)

@night wagon can you format it to lua?

[gritty mirage]

It's because you are not giving the player object to the function setUpPlayerData

You are essentially trying to get the userId from nothing

[night wagon]

How should I fix this?

[gritty mirage]

Just connect the function to the connection
Players.PlayerAdded:Connect(function(player) --put the code in the function here end)

[night wagon]

Oh ty that worked to fix the issue also I just realised the other reason why it couldnt work was actually because of an extra bracket at the back of the connect save code

"Attempt to put userID with nil" is not a real error

It's best you send a copy of the original message
